A field test is used to measure the density of crude oil recovered during a fracking* operation. The crude oil recovered is mixed with brine. The oil and brine mixture are placed in an *Hydraulic fracturing (or “fracking”) is a method that is used to recover gas and oil. Fracking creates fractures in rocks by injecting high-pressure liquids containing particulate additives into smaller cracks and forcing the cracks to widen. The larger cracks allow more petroleum products to flow through the formation to the well. A density test as described here could be performed to make a preliminary determination of the approximate makeup of the oil. The brine must be disposed of after fracking. open tank and allowed to separate. After separation, a 1.0 m layer of oil floats on top of 0.55 m of brine. The density of the brine is 1030 kg/m³, and the pressure at the bottom of the tank is 14 kPa gage. Find the density of the oil.
